Alcohol

Definition:

The term alcohol refers to a family of chemicals that occur widely in nature
and are mass-produced for use in antifreezes, fuels and some manufacturing
processes.

Alcohol is commonly used to refer to alcohol-containing drinks such as wine,
beer and spirits. In this case the alcohol, ethanol, has been produced by a
process called fermentation. Consumption of
excessive amounts of alcohol can lead to drunkenness and may be harmful to
health.
